HydroLogic® Stealth-RO150™ Membrane

HydroLogic® Stealth-RO150™ Membrane for For Stealth-RO 150 and Stealth-RO 300 Systems (HL22121)

The RO Membrane filters water down to the microscopic level, allowing nothing bigger than a water molecule through. Hydro-Logic membranes are standard equipment in our SP, CHP, MPRO, MPDI RO/DI, and the MPDW Drinking Water Systems. All 25 to 90 GPD membranes will fit in our standard membrane housing. The Standard Membrane is also available as a replacement option for most competitors' reverse osmosis systems. Replace membranes when product water decreases and/or ppm increase. Stealth RO150/300 membranes reduces 98%+ of total dissolved solids.

Replace membranes when product water decreases and/or ppm increase. Merlin Garden Pro and Evolution RO1000 membranes reduce 94%+ of total dissolved solids. Stealth RO100/200, Stealth RO150/300 and microRO-75 membranes reduces 98%+ of total dissolved solids. The Evolution RO1000 and Merlin Garden Pro systems need two (2) membranes. For all membranes, RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output.

About this item

• 98+% PPM Rejection
• 1 membrane for stealth-RO150 and 2 membranes for the stealth-RO300
• Filters up to 150 GPD (gallons per day)
• Replace between 6 months to 2 years

RO output depends on the source water temperature. At 77°, the system should produce 100% of the rated output. As the temperature drops or increases, so does the output.

THERE ARE TWO INDICATIONS AS TO WHEN TO CHANGE YOUR MEMBRANES

1. Test the RO and source/inlet water to see what percentage of the inlet water’s PPM the Stealth-RO150 is filtering out (rejection %). You should see approximately 98% of the inlet PPMs being removed when the membrane is new. If the rejection % falls under an acceptable level (typically 90%) it’s time to change the membrane
2. When the flow rate of the product water slows down significantly. This can also happen if your pre-filters are clogged. If you change your pre-filters and the product water still flows slowly then it’s an indication you need a new membrane. When it doubt contact HydroLogic

Flow rates of RO systems are based on source water @ 65 psi / 77° / 500 ppm
